Did I ruin my supply ? Help

Jenny • JJ 💙 👼👼👼👼

I used to pump one a day or twice if I was in the mood cause baby wasn’t latching. Then I gave up I stop pumping my breast went kinda back to normal but I still wear does pads so I won’t leak on my bra. Then my baby got a cold his 6 weeks so I try again with breastfeeding him he finally latch on my right side not my left but I notice my great haven’t gone bigger again. So I breast feed him but he only stay for 3 minutes and cry I knew there wasn’t enough milk so I feed him formula. I then took my pump to see my result there it’s it’s not even an ounce of mil from both of my breast. I’m so disappointed on myself I gave up to early scared my supply is drying up. Advise please how many times to pump or what should I eat to increase it back please I want to continue breastfeeding him now that he got a hang on it.

I used to pump in the beginning and will get 4oz-6oz each breast now not even one ounce help 😫
